폐기물 소각 시설에서의 다이옥신 배출 저감 기술 현황

다국어 초록 (Multilingual Abstract)

Dioxin was first known to the world as an impurity agent of the defoliants used in the Vietnam War. It is known to be one of the most dangerous environmental pollutants that cause hormone imbalance even at very low concentrations, leading to the deterioration of reproductive function and malformation of reproductive organs. Among various sources of dioxins, solid waste incinerators are known to be the largest emission sources. In Korea, dioxin emissions have been regulated in waste incinerators since 1999, and waste incineration facilities have been forced to reduce dioxin emissions through various methods. In order to minimize the emission of dioxin from the incineration facilities, the reducing technologies are classified as follows: the homogenization of the waste (step 1), the minimization of dioxin generation through complete combustion in the incinerator (step 2), the suppression of dioxin re-synthesis in the incinerator and post-treatment processes (step 3), and finally, the installation of the flue gas treatment utilities for reducing dioxin (step 4). In order to reduce dioxin emissions considering economic efficiency, it is desirable to optimize the unit processes from a medium-integrated point of view. When designing a new incineration facility or deriving improvement points of existing facilities, it is important to select suitable flue gas treatment utilities, considering the characteristics of each unit process before the flue gas treatment steps. In this paper, we introduce the various methods before the flue gas treatment steps and the flue gas treatment utilities, respectively.
